Differences in texture features in geometrical measures and Renyi dimensions categories between each pair of groups of preinvasive lesions, MIAs and IPAs

Category	Texture features	P value
		Preinvasive lesions vs. MIAs	Preinvasive lesions vs. IPAs	MIAs vs. IPAs
MIAs, minimally invasive adenocarcinomas; IPAs, invasive pulmonary adenocarcinomas; *, statistical analysis using analysis of variance (ANOVA) followed by Tukey’s HSD post hoc test, otherwise using a Kruskal-Wallis rank sum test followed by Dunn-Bonferroni post hoc test.
